When caste data is there but isn't released

Even as the central government plans to conduct a caste census across the country, Karnataka has data on the socio-economic data of backward castes in the states for nearly a decade that it hasn't released fully.

Political analyst and author Sugata Srinivasaraju explains the partial release of data and why the state may have inspired caste-based reservations in India in the past, it hasn't done very well with the current survey's data.
